Hadrat Ali (Radhi Allahu Anhu) reports that
Rasulullah (Sallallahu Alayhi Wasallam) said,
'When a Muslim visits his sick Muslim brother in the morning, seventy thousand
angels make dua for his forgiveness till the evening. And when he visits him in the
evening, seventy thousand angels make dua for his forgiveness till the morning,
and he will be granted a garden for it in Jannah.'
